Several underwater-applied epoxy coatings were developed for protecting steel structures 

 in seawater. The more promising formulations were laboratory and field tested at different times 

 using a brush, a roller, and a curved plastic applicator developed by the Navy Coastal Systems 

 Laboratory. The coating that was the easiest to apply underwater is now marketed by a commer- 

 cial supplier. Sandblasting was found to be the best method of preparing steel surfaces for paint- 

 ing underwater, and waterblasting was the next best of the five methods tested.
